“(BCN3D)’s unusual business proposition of half 3D printing products and half 3D printing education (stemming from their close association with academic courses and university research labs) could lower the entry barrier for those uninitiated in 3D technologies, and could create a much wider pool of certified and skilled 3D printing users.” - 3DPrintingIndustry.com

We're proud to announce new and improved dual extrusion from E3D. Chimera+ and Cyclops+ are swappable HotEnds designed specifically for both air- and water-cooled dual extrusion.
Cyclops+ is a two-filament, one-nozzle HotEnd specifically designed to switch between two colours. There’s never an idle nozzle oozing while the other is printing (so there's no need for an ooze...

We all know about the age-old overhang problem: The inability to print features that overhang beyond a certain angle.
Same-material breakaway supports are far from a perfect solution - even with some really great algorithms out there you’re still never going to be able to extract support out of an awkward internal cavity, or deep screw hole...

For a long time we’ve wanted to do something that takes care of dual extrusion in a neat and simple package. So we started out with some design objectives:
Simple and easy to use, mount, and maintain
Modular, upgradable, and compatible with the v6 ecosystem
Lightweight and compact
More cost effective than mounting two E3D-v6 HotEnds side...
